What to do with Petechial Rash on Leg

Petechial rashes

Petechial rashes

Petechial rashes are rashes that look like pin points, are reddish in color and are flat unlike regular rashes. Petechiae are due to conditions that make blood vessels beneath the skin rupture and bleed. Petechial rashes may appear at any area of the skin; the most common areas where these rashes develop are the face, the neck, the abdomen, on the legs, arms and on the trunk. It is likely that petechial rashes are caused by pressure or trauma on the area. Rigorous scratching bumps and scrapes on the skin can lead to petechiae. Straining may cause petechiae on the neck, face, arms and on the legs.

What to do with petechiae on the legs and extremities?

Most petechial rash cases resolve on their own; you don’t need to use remedies, treatments or take medications to manage this condition. However, in severe cases, there are further treatments that need to be done. Here are some techniques to consider:

  • The underlying factor or medical condition must be treated to totally manage the spread of petechial rashes. For instance, if the petechiae are caused by a viral illness then viral treatment is commonly prescribed. If the rashes are caused by a decreased platelet count then taking medication or blood transfusion is often done in severe cases.

  • In mild cases, petechiae on the legs may disappear on their own. But the best way to deal with petechial rashes is to apply cold compress. Cold will reduce rupture and bleeding of blood vessels. You need to apply cold compress for 15 to 20 minutes for at least a day for minor petechial rashes.

In severe cases when petechial rashes form purpura (large patches of rashes), it could be very difficult to apply cold all over the legs; staying on an air conditioned room will help cool you down or you may use ice packs instead.

  • Avoid activities like heavy lifting, straining, walking or standing for a long period of time to prevent worsening your condition. There are special footwear and stockings to help you reduce pressure on your legs especially when you need to walk or stand for prolonged periods.

  • Take a rest and elevate your legs. Resting helps the body recuperate from bleeding and will also help the body repair tissues. Elevating the legs will also reduce bleeding since you are deviating fluid away from the lower extremities. If you can, lie down with two or more pillows under your feet; if you are just resting, avoid hanging your feet from a seat or a bench.

  • Take care of the skin on your legs. Skin that has petechial rashes may be more vulnerable to dryness and skin disorders. Petechial rashes may progress into purpura and ecchymoses which are characterised by reddish to purplish rashes that may develop into vesicles and later become ulcerated. Drink a lot of water, apply moisturizers on the area. Do not overlook petechial rashes no matter how simple they may be for these may be symptoms of an underlying illness. Consult your doctor at once for any symptoms.
